Yes it has, at least well enough to where I'm not longer looking for pedals anymore (bad addiction for years lol)
This isn't to say the Axe is perfect at everything, but its good enough to where when I'd go out and buy/rebuy a dedicated pedal, it didn't really seem to warrant the cost and hassle patching it into a loop.
Caitlinbread Echorec for example.....awesome pedal for what it did, and a little better than what I can get out of the Axe....BUT..... was it $230 better for an effect I really don't use that much ? Not really...... and again it meant having to patch it into my chain, having to worry about knob settings which don't magically change per patch like the effects on the Axe etc.
In the end the Axe just proves to always be "good enough", and also a huge time/money saver.
Are the Axe fuzz sounds perfect ? Again nope, but the number of hours, and losses I had buying/trying/selling all the hot at the moment fuzzes from Skreddy, Wren and Cuff etc really added up fast. I'd end up losing hundreds of dollars in a month doing this, thinking every next pedal would be "the one".
With the Axe I've just learned to accept it does what it does well enough, and to stop looking/reading/buying TGP forums and such.
Maybe if I had unlimited funds I'd still have a huge pedal collection, wouldn't we all lol, but I'd probably still have just an Axe rig set up and always ready to play.....
Back when I had a collection of 30-40 pedals I could almost never even play them because nothing was patched together or dialed in. I'd spend 45 minutes picking which pedals I wanted, a/b'ing them against another pedal I was thinking of selling etc.
So many choices took time away from actually playing (but was fun in its own way.....)
Long story short.... There aren't any tones that Axe can't get me well enough for my needs. Now sure it can't do everything, so no it won't replace, say a EHX C9 pedal that well, but that frankly isn't an effect I need for my music so its not missed.
In terms of delays, chorus, reverbs, amp sims, boost, OD's, wah, phaser etc. Axe handles it all nicely, and really anything lacking comes down to my playing ability.
Lets face it, there are dudes with some generic Boss pedals that just kill on guitar, like Prince, and then there are guys on forums with $10K worth of pedal board gear and sound like crap and can't play a lick really. They just have the money to buy fancy/rare gear on Ebay.
Bottom line for me these days is that as long as I can do my part as a player, the Axe is going to be able to produce world class sounds and I shouldn't ever need anything more
